Ball screw principle:

1. Ball screw lifting units, in accordance with the national standard GB/T17587.3-1998 and application examples, are used to convert rotational motion into linear motion; or linear motion into rotational motion, featuring high transmission efficiency and precise positioning.

2. When the ball screw lifting jack acts as the actuator, the nut will convert the rotational angle of the screw into linear motion according to the corresponding pitch specifications. The passive workpiece can be connected to the nut via the nut seat, thereby achieving the corresponding linear motion.

Ball screw features:

1、Ball screw has a driving torque compared to sliding screw.1/3

2、Ball screw features high precision

3、Ball screw micro feed

4、Ball screw with zero clearance and high rigidity

5、Ball screw high-speed feed possible.
